Ancient cartograph...

has been authenticated and dated to about 50 years prior to the voyage of Columbus. It clearly shows that Norsemen and other northern European explorers made it to North America (click to enlarge) as Hudson Bay and the St. Lawrence River are obvious features depicted on the continent (upper left corner.)

How were these explorations and discoveries possible? Why, climate warming of course. The Medieval Warm Period allowed for easy high-latitude westward expansion of Norse settlements and explorations.
